What is the primary role of the equilibrium constant (K) in a chemical reaction?

To indicate the direction of the reaction

To measure the amount of energy released

To determine the speed of the reaction

To calculate the temperature of the reaction

How is the equilibrium constant (K) calculated for a chemical reaction?

By dividing the concentration of products by reactants

By adding the concentration of reactants and products

By multiplying the concentration of reactants and products

By dividing the concentration of reactants by products

If a reaction is found to have a very small K value, what would be true?

The reaction favors the reactants.

The reaction has a high activation energy.

The reaction is at equilibrium.

The reaction favors the products.

If a reaction is found to have a very high K value, what is true?

The reaction strongly favors products.

The reaction is at equilibrium.

The reaction strongly favors reactants.

The reaction has a low activation energy.

What does a K value of 1 indicate about a chemical reaction?

There are more products than reactants

There are more reactants than products

How does increasing the temperature generally affect the equilibrium constant (K) of an exothermic reaction?

K decreases, favoring reactants

What is the significance of a very large K value in a chemical reaction?

The reaction strongly favors products

The reaction strongly favors reactants

What happens to the equilibrium position when the K value is less than 1?

The reaction favors the formation of reactants

The reaction becomes irreversible

The reaction favors the formation of products
